I can't imagine this working for the simple reason that an interaction with a Starbucks barista (or really any person providing service for a major food and drink chain) is entirely passive, mechanical and strictly limited to the transaction being made. I'm sure you could throw in a few seconds of smalltalk out of courtesy, but nothing remotely resembling a profound conversation in race relations. Now, this definitely could work in small coffee shops, which often serve as informal gathering places for certain groups in a given municipality or social circle. But then you wouldn't need to set up any particular campaign to encourage racial conversations - you already discuss everything to your heart's desire to begin with. The highly blunt way this is being presented and the inappropriate setting is bound for awkward situations galore.
